Yu Yifeng is not a crazy person, but he doesn't mind going crazy when necessary.

He followed the spider robot, walking cautiously. He was sure that they were on the road to the central area, and the robots were indeed controlled!

"Are you running out of donkey skills?"

He secretly thought in his heart, the other party is definitely a high-IQ species, maybe he knows that Yu Yifeng is about to find a way to crack it, so he can't help but test it with the spider robot under control, what if it succeeds?

This also reflects that the other party does not have a high ability to act.

Yu Yifeng also deliberately pretended not to know anything, and followed step by step.

"Bang bang bang", this is the sound of his heartbeat, Yu Yifeng felt that his breathing was thickened, and his heart was getting more and more nervous, and in the next moment, that dangerous and relaxed feeling suddenly appeared!

He...... Can't go any further!

Up front is your lair?! Without hesitation, Yu Yifeng put down He Xu who was carrying him quickly, took out the assault rifle suddenly, and pulled the wrench without hesitation, just "bang", and the spider robot was shot into scrap metal!

"Is this your lair! Lao Tzu doesn't want to go in! Yu Yifeng scolded fiercely, but then, he heard more mechanical running sounds, and more than two dozen spider robots quickly rushed over from the aisle!

They...... It's all under control!

They were originally war machines for the human military, but they were modified by scientists because of their different tasks. The weapon system in the abdominal cavity was removed and replaced with an exploration instrument.

But that doesn't mean they can't kill, and the eight metal legs under them are the best means of attack. These metal legs can be ejected like throwing knives, and the slightest cut through the spacesuit can cause the deadliest effect.

Because in battle, it is impossible to have time to repair the spacesuit. If you are stabbed, the air in your clothes will quickly drain away, causing danger such as loss of pressure and suffocation!

Yu Yifeng had already focused to the extreme at this time, and the more than two dozen fast-crawling spider robots still caused him huge psychological pressure. There was no time to aim one by one, so he directly raised the gun and shot, completely relying on his own consciousness and experience.

He heard only a series of crackling sounds, a jerk of his shoulders, and a huge recoil from his arm, which made him almost unable to stabilize his body.

“…… , gravity on Mars is still too low!"

This kind of kinetic energy weapon with too much recoil often has to forcibly stabilize the body after firing a shot. It's good now, a series of bullets are fired, where is it still stable?

However, his reaction speed was really fast, and after pulling the trigger, the push force from his arm, coupled with the power in his waist, suddenly exerted it, which actually made his whole person rotate more than a hundred degrees, just facing the one-degree wall.

Yu Yifeng bit his lip tightly, stepped on the wall with some cracks, and rolled violently with this force.

"Three!" In an instant, the three robots had been beaten into scrap metal by bullets.

These spider robots were created by humans, and his weaknesses are best known, their shells are not thick and they are not resistant to beating!

“…… Still want to use human half-finished weapons against me? ”

But in the next moment, a few more robots pounced in front of them, and they didn't care about He Xu on the ground, which also made Yu Yifeng firmly believe: "The things inside, I want living creatures!" ”

“…… It knew it couldn't control me, so it wanted to kill me! At least He Xu can be left! ”

Between the lightning and flint, such an idea suddenly burst into Yu Yifeng's mind, but it was only a flash.

His full attention was focused on the three droids in front of him. A casual glance out of the corner of his eye revealed that several of them had also appeared behind him, and the lights on their electronic eyes were all turned off, moving at full speed in the pitch darkness.

"Why are there so many!"

Seeing several robots jump high, and several front paws about to fly out, his breathing stopped. Time seemed to slow down a lot at this moment, Yu Yifeng turned to the side suddenly, hooked his finger again, and shot at the gun.

The flames erupted from the muzzle of the gun, hitting the abdomen of several robots with precision, and their bodies were scuffled and immediately knocked out of the air, with a trace of electric sparks on their bodies.

It was only a blink of an eye, but a series of flying knives had already come in front of Yu Yifeng!

His pupils dilated slightly, and he jumped suddenly, making another incredible evasive move. At the same time, a series of bullets happened to bring a strong recoil, lifting his whole person up a little more, and several throwing knives happened to pass underneath!

"Six!"

He stepped out of the wall in front of him again, swerved sharply, and fired sharply. In the nick of time, a series of blades hit the wall at the side of the blade.

These blades are the metal legs of the spider robot, made of special human materials, and the hardness is not comparable to that of alien metal, so they do not shoot into the wall, but just fall to the ground one by one.

"Eight!"

At this time, he shot two other robots, also with the help of the recoil of the gun, moving his position, constantly dodging and somersaulting......

No one was watching, only the surveillance equipment on the spacesuit faithfully recorded all this.

And the creatures behind these robots, I don't know if there is a concept of surprise, in short, this battle has completely exceeded the limits of human beings!

Yu Yifeng used the recoil of the firearm, coupled with the strength of his whole body, to keep jumping back and forth between the two walls, each time the time interval was no more than a second, and a sharp blade that flew out from the handle could always flash at the last moment.

This has to be said to be a kind of fighting instinct and skill!

The assault rifle in his hand fires a barrage of bullets, almost every shot that hits a spider robot, and the battle situation is becoming more and more fraught......

"Twelve!"

In just one minute, there were twelve more scrap iron on the ground, and scrapped electric sparks flashed on his body from time to time. But at this moment, Yu Yifeng had also jumped into a dead corner, and he had almost no way to dodge!

"Smack!" With a thud, his chest was cold, and a sharp pain came from his chest. He immediately took a big breath, calmed his mind, and "snorted", a large amount of gas was leaking out quickly from the gap, and he had to hurry!

"Each robot can only fire four blades, and the speed is more than 100 meters per second, but fortunately, the spacesuit is relatively tough, and it is slightly blocked, otherwise I may be worn through this time!"

He didn't dare to hesitate, and in this interval, he jumped forward with all his might, while shooting non-stop.

This assault rifle has 30 rounds in one magazine, and if you hit them all, the bullets are completely sufficient.

"Seventeen!"

In just an instant, Yu Yifeng had already burst out of the encirclement, but the price that followed was that he was also hit on the leg.

The two holes were leaking fast, and he took another hard breath of air, which was probably the last. He gritted his teeth and twisted his body sharply, facing the last four droids.

"Bang bang bang", the assault rifle spat out a merciless tongue of fire, knocking them all to shreds.

"Twenty-one! Come to an end! ”

After doing this series of actions, Yu Yifeng felt sore all over his body, and his physical strength was very exertional, especially since the whole head already had symptoms of hypoxia. But there is no oxygen in the spacesuit, and he must hurry up to repair the spacesuit, otherwise there is a danger of suffocation.

He took three steps and two steps, ran to the edge of the toolbox, and pulled out the two sharp knives on his chest and legs, because they were blocked by the spacesuit, the wound was not very deep, but the blood kept flowing out. Yu Yifeng took out a sticky bandage and applied it indiscriminately to stop the bleeding.

The spacesuit is torn, the gap is not very large, and it can be temporarily repaired with eraser, glue and other tools.

His speed was very fast, although the time was tight, but his hands were still calm, and it took about 30 seconds to touch, and when he was about to lose his breath, the spacesuit was finally repaired.

Yu Yifeng hurriedly hung up the spare oxygen cylinder, the air rushed in quickly, and the whole clothes bulged again. He took a few big breaths, feeling a dull pain in his lungs, probably because the air pressure was close to a vacuum just now.

"Fortunately, the rifle shell didn't hit him......" Yu Yifeng reviewed the battle just now, and was also glad that he was lucky, in this small space, the bullet may jump several times, and it may bounce to himself, or He Xu on the ground.

Thankfully, that didn't happen.

"Now it's my turn!"

He sneered and looked around, and after confirming that there were no more spider robots, he finally picked up the Gauss rifle on the ground, aimed at the darkness in the distance, and pulled his finger......

"Boom!"
